The variable-speed belt on the Clausing 5914 lathe (made in 1972) looks a bit worn, has already lost a number of cogs, and the other cogs are cracked, so belt replacement is in order. The timing belt looks OK, but I may replace both, as it's such a chore, requiring partial disassembly of the powertrain.
My questions are what belts (by make and model) are correct, where can one buy them, and what should they cost? (I imagine one can get them from Clausing, but at a substantial markup.)

RD Burch in another thread suggested that 1930V400 is the industry designation for the belt but he may have gotten that from the earlier thread. Later he mentions that 1922V400 may be a better fit, based on sheave angle.
James Casey talked about Goodyear "1930v400 variable speed belt and
630h150 timing belt" in a 12/2003 post and seemed to think that they worked out OK.
Sorry - no post numbers for any of the above.
From another forum, a member there suggests that Browning 1930V400 is the right belt.
If you still have the original belt, why not take it to a bearing house and get them to cross reference it for you? My local Motion Industries (Berry Bearing) outlet has been helpful for that in the past.
I cannot figure out which belt is which from the Clausing pricelist of November 2005, but "timing belts" go for about $200, and "belts" for about $100, although there are lots of cheap belts that I assume are not for powering the spindle.
I tried to post the same question on the yahoo Clausing group, but nothing happened. I'm a new member, and I assume that the Moderator has not yet released this my first posting.
The variable-speed belt is on the machine is made by Goodyear and has "1930V400 64" molded into the rubber.
The timing belt has no markings that I could find.
The timing belt is 1.5" wide and has two teeth per inch. I'll have to count the teeth, but given the count finding the correct timing belt should not be hard. The above number would be a good starting point.
It appears that 1930V400 is an industry-standard number.
I can certainly do this, but I figured that I am not the first to replace the belts, so the answer or answers should already be known. And it seems that they are.
You can search from the groups.yahoo.com web page for the clausing group.
There is a gent with the last name Webb that is likely your best source of info. I have a 6903 and don't know the differences between that one and yours.
I sure wish winter would end. I'd like to finish repairing mine and get to using it. 7F atm. Having a warm streak.
